I think OP is saying that they have an old 3d printer that they made/love, and their spouse got them a new (better, nicer looking, but less sentimental) 3d printer.
"The one I have was given to me by my mother in law, whom I adore. It’s sentimental. ... it was a kit and I had to build myself. I loved it. It’s perfect for me. "
I think from a factual basis your position sounds perfectly reasonable, I feel similarly about new things. (Perhaps there are other parts of the story missing though?)
There's a lot to be said for delivery. If you opened a gift an reacted badly immediately, that would hurt. Even if the gift was misjudged, it was probably meant with good intent. Accepting thankfully, acknowledging the intention, and THEN coming around to the "but you really should have checked in first for something like this" might be a good way to start.
Yeah, I think AI optimising commercial music genres is just effectively doing what the corporate music industry has been doing for years anyway. It's like gamification of the auditory processing system.
It is possible for genAI to be creative in that sense (e.g. move 37), but it's not possible for it to know whether that new thing is good/valuable/true/whatever. So it can't challenge an idea in any sense more meaningful than a monkey throwing darts. A human could use it to generate challenges, and then evaluate them, but that's a different proposition.
On your first point, I think it's not so much about reputation as about trust. Long-standing accounts at least have the simple trust that's based on consistency and familiarity. If you meet a new person IRL, you at least get something to go off based on visuals and behavioural cues. A new account online has absolutely nothing to base any trust on.
In a smelter, so they can be recycled into bikes and trains.
